I need to find out if the TextBox control contains a HTML comment but without closing tag. e.g. <!-- content here notice that it's possible that they can enter more than one comments so all of the comments have their closing tag except one (or even more).
I just need to find if there is ONE or more html comments without closing tag.
I have the following string:
<TD><!-- 1.91 -->6949<!-- 9.11 --></TD>
I want to end up with:
<TD>6949/TD>
But instead I end up with just the tags and no information:
<TD></TD>
This is the regular expression I am using:
RegEx.Replace("<TD><!-- 1.91 -->6949<!-- 9.11 --></TD>","<!--.*-->","")
How to keep the numbers and remove just what the comments.
I'm using this script:

View 3 RepliesIm working on a comment control. I mean a control, that has an input area for text and images and a line or an arrow for pointing to something. It should a bit look like the comment control in Adobe Acrobat.
My first idea is to put four standard controls together:
1) a RichTextBox to hold text and images
2) a Panel to hold the RichTextBox and some GrabRectangles around it (the Panel needs to be a bit greater than the RTB for the GrabRectangles)
3) a little Panel (3x3 or 4x4 Pixel) to hold another GrabRectangle for placing and resizing the line (the arrow)
4) a LineShape for pointing (its startpoint on the RTB and endpoint on the little Panel)
I have added a drawing.My question is: what can I use to put these controls together? Another Panel would probably do a good job. But it would cover a lot of additional area around the contained controls and hide other controls, so that they dont get mouse clicks.

View 5 RepliesI have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

How can you find a specific HTML element in a webbrowser.document? I'm making a program that will go to a specified address on the internet and find a html element and get the src link from the element then return the src to the imagelocation of a picturebox. Is this at least possible?
View 8 Repliesso I had an idea today while modding a game I play. I decided to make a mod-manager.In order to start the game with mods, you have to go to the website, log in, click playnow and view the source of the html file. From there you get the sessionID variable and add it to a shortcut on your desktop. I wanted to be able to automate this process by doing the following:
on button1.click: somehow parse the source of the html file to locate the line that looks like chis:
var sessionId = 'random26charSessionID'; and take what is inside of the ' ' and add it to textbox1.text
Any ideas? Not sure if it will be in the same line every time with add banners and stuff...so I wanted to parse the doccument.
Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?
Dim frm As Form

The above code is what I used in VB6 to close all forms associated with my programs before my program closed. I have been searching for information on how to make sure all forms are closed when closing a VB2008 program.
I have seen info on using the Project Property Shutdown mode When startup form closes and I currently have this set.
Is this all that is really necessary? Will the garbage disposal close everything else to free up RAM?
Also, if I have several forms open and want to close all from the main form without closing each one individually, what is the best approach? Is there a collection like in VB6, go through the collection, compare it to the name of the main form and close it if it is not the main form?

Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?
I'm in the middle of a program, and this one is completely stumping me.GOAL: user enters HTML into a text box, presses a button, and the webbrowser displays the page resulting from the code.

AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
